Beschreibung
Zusammenfassung:	A vehicle driving apparatus includes: an engine; a fluid transmission device; first and second rotary electric machines; an output shaft for receiving a power transmitted through a first power transmission path and outputting the power to one of a pair of front wheels and a pair of rear wheels; and a control device for controlling an engine operation point by adjusting an electrical path amount between the first and second rotary electric machines. The second rotary electric machine outputs the power to the other of the pair of front wheels and the pair of rear wheels, through a second power transmission path. The control device obtains a target electrical path amount enabling the engine operation point to become a target operation point, and causes a speed change device provided in the second power transmission path to establish a gear ratio enabling the target electrical path amount to be attainable.
